Abstract

PURPOSE: At a variable frequency oscillator, the lock state of an AFC circuit is discriminated by pulses obtained according to existence of a pulse interval, thereby stopping the phase-comparing operation of the AFC circuit at the time of the variation of the interval of regenerated horizontal synchronous signals.
